9. COMPUTER AIDED
MANUFACTURING (CAM)
Implies manufacturing itself ,aided or controlled
by computers.
ADVANTAGES OF CAM
1. Greater design freedom
2. Increased productivity
3. Greater operating flexibility
4. Shorter lead time
10. COMPUTER INTEGRATED
MANUFACTURING (CIM) SYSTEM
The integration of CAD (computer
aided design) and CAM (computer aided
manufacturing) systems is called
computer integrated manufacturing
(IM).
CAD + CAM CIM SYSTEM
